Die for powder metallurgy capable of cleaning metal powder in die automatically

Abstract

The invention relates to the technical field of powder metallurgy and discloses a die for powder metallurgy capable of cleaning metal powder in the die automatically. The die comprises a lower die. Adie slot is formed in the top of the lower die, a first chute, a straight slot and a second chute are formed in the lower die, a powder outlet trough is formed in the right side of the lower die, a first guide block is rotatably connected in the first chute, a fan is arranged on the right side of the first guide block, a first driven wheel, a driving wheel and a second driven wheel are arranged inthe straight slot, and a second guide block is rotatably connected in the second chute. As the driving wheel rotates, the first guide block slides rightward and the second guide block slides leftward, so that the fan stretches into the die slot, the die slot communicates to the powder outlet trough, powder in the die slot falls into the powder outlet trough, and the fan is started to blow the powder attached to the inner wall of the die slot into the powder outlet trough, and therefore, an effect of cleaning the powder in the die slot thoroughly is achieved.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to a powder metallurgy mold for automatically cleaning metal powder in the mold. Background technique [0002] Powder metallurgy is a process technology that uses metal powder and non-metal powder as raw materials to manufacture various products through forming and sintering. Powder metallurgy technology has a series of advantages because of its significant energy saving, material saving, excellent performance, high product precision and good stability. , very suitable for mass production, so very dynamic. [0003] In the process of powder metallurgy products, there will be cases of pressing failure due to insufficient pressure. It is necessary to clean up the metal powder in the mold. Failure to clean up may lead to uneven density of the finished product that is pressed again. The powder that is pressed and agglomerated can be used The fixture is taken out, but it is inc...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a mold for powder metallurgy that automatically cleans the metal powder in the mold, which can automatically clean the fine powder in the mold after the failure of the product process, without affecting the continuous operation of the machine and improving work efficiency. Advantages, it solves the problem that the fine powder in the mold is difficult to clean after the failure of the product process, which affects the continuous operation of the machine and reduces the work efficiency.
